■elevated in the basal two-thirds, which is separated from the 

 anterioi' part by a deeply bisinuate impressed line, the elevation 

 is much highest in the centre, where it forms a very prominent 

 callosity bearing a short deep cenLral furrow ; among the scaling 

 ■are some scattered shoi't squamiform sette, which also form a 

 •sparse fringe along the basal margin. Elytra broad, subquadrate, 

 deeply and jointly bisinuate at base ; sides obliquely dilated to 

 some distance from base, forming a prominent humerid angle, 

 and from there gradually narrowed to the apex ; upper surl'ace 

 convex, Avith fine stria? containing rows of large punctm^es (only 

 visible when the scaling is removed) ; the intervals broad, slightly 

 convex, shiny and finely aciculate ; intervals 3 and 5 * are 

 elevated at the base, and the latter bears also a tubercular 

 prominence which projects horizontally from the declivity and 

 is much larger in the c? than in the $ ; each interval has an 

 irregular row of very short depressed squamiform sette. Legs 

 normal, set with short, pale, sviberect sette. 



Cape Colony: East London {Dr. G. B. Longstaff, Sept. 1905). 



Type in the Oxford Museum. 



This species is somewhat intermediate between E. pulvinati- 

 coUis Boh. and E. hidentatus Boh. In the former the structure 

 of the thoi-ax is very similar, but the insect is much larger, the 

 elyti'a are more elongate and show no traces of the basal or 

 posterior callosities. In size and facies caUosicoUis much re- 

 sembles bidentatus, but in the latter species the thorax is simple 

 and the elytra huve no basal callosities. 



Zeugorygma, gen. nov. (Tanyrrhynchides.) 



Head hemispherical ; the eyes widely separated, convex. Rostrum 

 rather longer than the head and prothorax, strongly curved ; ruider 

 surface as densely squamose as the upper ; scrobes f oveif orm, 

 placed very close together on the upper surface* in front of the 

 middle and with a very fine stria connecting them with the apex. 

 Antennce with the scape reaching nearly to the middle of the 

 prothorax ; the two basal joints of the f uniclo very elongate, 

 the second slightly longer than the first. Prothorax transverse, 

 broadest at base and rapidly narrowed to apex ; basal margin 

 arcuate ; apical margin subtruncate clorsally, slightly lobate 

 laterally and without vibriss?e ; the anteiior coxa? placed aboiit 

 in the middle of the prosternum. Elytra ovate, with oblique 

 shoulders and with 10 finely-punctured striae ; the intervals 

 smooth, almost plane, and with rows of very long erect hairs. 

 Legs stout ; femora unarmed, posterior pair not reaching the 

 apex of the elytra ; tibife straight, anterioi' pair not denticulate, 

 corbels of posterior pair enclosed ; tarsi short and broad, the 

 second joint shorter and narrower than the first and third, fourth 

 joint short, the claws small and connate. Abdomen with the 



* The space between the suture and the tirst stria is reckoned as the first interval.
